1Spatial distribution of atmospheric water vapor and its relationship with precipitation in ,summer over the Tibetan Plateau显示文摘By using the observed monthly mean temperature and humidity datasets of 14 radiosonde stations and monthly mean precipitation data of 83 surface stations from 1979 to 2008 over the Tibetan Plateau(TP),the relationship between the atmospheric water vapor(WV) and precipitation in summer and the precipitation conversion efficiency(PEC) over the TP are analyzed.The results are obtained as follows.(1) The summer WV decreases with increasing altitude,with the largest value area observed in the northeastern part of the TP,and the second largest value area in the southeastern part of the TP,while the northwestern part is the lowest value area.The summer precipitation decreases from southeast to northwest.(2) The summer WV presents two main patterns based on the EOF analysis:the whole region consistent-type and the north-south opposite-type.The north-south opposite-type of the summer WV is similar to the first EOF mode of the summer precipitation and both of their zero lines are located to the north of the Tanggula Mountains.(3) The summer precipitation is more(less) in the southern(northern) TP in the years with the distribution of deficient summer WV in the north while abundant in the south,and vice versa.(4) The PEC over the TP is between 3% and 38% and it has significant spatial difference in summer,which is obviously bigger in the southern TP than that in the northern TP.ZHOU Shunwu WU Ping WANG Chuanhui HAN Juncai 2012Journal of Geographical Sciences2012,22,5:15
2Two-dimensional heterostructure promoted infrared photodetection devices显示文摘It is a rapidly developed subject in expanding the fundamental properties and application of two-dimensional(2D)materials.The weak van der Waals interaction in 2D materials inspired researchers to explore 2D heterostructures(2DHs)based broadband photodetectors in the far-infrared(IR)and middle-IR regions with high response and high detectivity.This review focuses on the strategy and motivation of designing 2DHs based high-performance IR photodetectors,which provides a wide view of this field and new expectation for advanced photodetectors.First,the photocarriers'generation mechanism and frequently employed device structures are presented.Then,the 2DHs are divided into semimetal/semiconductor 2DHs,semiconductor/semiconductor 2DHs,and multidimensional semi-2DHs;the advantages,motivation,mechanism,recent progress,and outlook are discussed.Finally,the challenges for next-generation photodetectors are described for this rapidly developing field.Gaofeng Rao Xuepeng Wang Yang Wang Peihua Wangyang Chaoyi Yan Junwei Chu Lanxin Xue Chuanhui Gong Jianwen Huang Jie Xiong Yanrong Li 2019InfoMat2019,1,3:12
3Electroacupuncture regulates glucose-inhibited neurons in treatment of simple obesity显示文摘The glucose-inhibited neurons present in the lateral hypothalamic area are regarded as glucose detectors. This structure is involved in the regulation of food intake through extracellular blood glucose concentrations, and plays a crucial role in obesity onset. In the present study, obesity models established with high fat feeding were treated with electroacupuncture at Zusanli (ST36)/ Inner Court (ST44) on the left side and Tianshu (ST25) bilaterally. We found that electroacupuncture could effectively reduce body weight and the fat-weight ratio, and decrease serum leptin, resistin, tumor necrosis factor alpha, and neuropeptide Y levels, while increase serum adiponectin and cholecystokinin-8 levels. This treatment altered the electrical activity of glucose-inhibited neurons in the lateral hypothalamic area, with electroacupuncture at Zusanli/ Inner Court exerting an inhibitory effect, while electroacupuncture at bilateral Tianshu exerting an excitatory effect. These data suggest that electroacupuncture at the lower limbs and abdominal cavity is an effective means for regulating the activity of glucose-inhibited neurons in the lateral hypothalamic area and for improving the secretory function of adipose tissue.Zhi Yu Youbing Xia Chuanhui Ju Qinghua Shao Zhen Mao Yun Gu Bin Xu 2013Neural Regeneration Research2013,8,9:11

5Comparative investigation of three types of ethanol sensor based on NiO-SnO_2 composite nanofibers显示文摘NiO-SnO2 composite nanofibers were synthesized via electrospinning techniques and characterized by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,and X-ray photoelectron spectroscopy.Three types of sensor were applied to investigate the sensing properties of these nanofibers.Sensors A were fabricated by mixing the nanofibers with deionized water,and then grinding and coating them on ceramic tubes to form indirect heated gas sensors.Microsensors B(with an area of 600 μm×200 μm) were formed by spinning nanofibers on Si substrates with Pt signal electrodes and Pt heaters.Sensors C were fabricated by spinning nanofibers on plane ceramic substrates(with a large area of 13.4 mm×7 mm) with Ag-Pd signal electrodes only.The operating temperatures of sensors A and B were controlled by adjusting heater currents,and the operating temperatures of sensors C were controlled by adjusting an external temperature control device.Experimental results show that sensors C possess the highest sensing properties,such as high response values(about 42 to 100 μL/L ethanol),quick response/recovery speeds(the response and recovery times were 4 and 7 s,respectively),and excellent consistencies.These phenomena were explained by the retained fiber morphology and suitable sensor area.The presented results can provide some useful information for the design and optimization of one-dimensional nanomaterial-based gas sensors.SHEN RenSheng LI XiangPing XIA XiaoChuan LIANG HongWei WU GuoGuang LIU Yang CHENG ChuanHui DU GuoTong 2012Chinese Science Bulletin2012,57,17:5
6Microstructure and Tribological Properties of Plasma Nitriding Cast CoCrMo Alloy显示文摘A medical cast CoCrMo alloy was coated by plasma nitriding process to enhance the wear resistance.The microstructures,phases and micro-hardness of nitrided layers were investigated by atomic force microscopy(AFM),scanning electron microscopy(SEM),X-ray diffraction(XRD) and micro-hardness.Tribological properties were investigated on a pin-on-disc wear tester under 25% bovine serum solutions.The experimental results showed that plasma nitriding was a promising process to produce thick,hard and wear resistant layers on the surface of CoCrMo alloy.The harder CrN and Cr2N phases formed on the plasma nitrided layer with the compact nano-crystalline structure.Compared with the untreated sample,all nitrided samples showed the lower wear rates and higher wear resistance at different applied loads and nitriding temperatures.It was concluded that the improvement of wear resistance could be ascribed to the formation of thicker and harder nitrided layers with the specific microstructures on nitrided surfaces.Qingliang Wang Chuanhui Huan Lei Zhang 2012Journal of Materials Science & Technology2012,28,1:3
7Investigation of phosphate adsorption from an aqueous solution using spent fluid catalytic cracking catalyst containing lanthanum显示文摘A spent fluid catalytic cracking (FCC)catalyst containing lanthanum (La)was used as a novel adsorbent for phosphorus (P)in simulated wastewater.The experiments were conducted in a batch system to optimize the operation variables,including pH,calcination temperature,shaking time,solidliquid ratio,and reaction temperature under three initial P-concentrations (C0=0.5,1.0,and 5.0mg/L). Orthogonal analysis was used to determine that the initial P-concentration was the most important parameter for P removal.The P-removal rate exceeded 99% and the spent FCC catalyst was more suitable for use in low P-concentration wastewater (C0<5.0mg/L).Isotherms,thermodynamics and dynamics of adsorption are used to analyze the mechanism of phosphorus removal.The results show that the adsorption is an endothennic reaction with high affinity and poor reversibility,which indicates a low risk of second releasing of phosphate.Moreover,chemical and physical adsorption coexist in this adsorption process with LAPO4 and KH2PO4formed on the spent FCC catalyst as the adsorption product.These results demonstrate that the spent FCC catalyst containing La is a potential adsorbent for P-removal from wastewater,which allows recycling of the spent FCC catalyst to improve the quality of water body.Zhen Li Zhaofu Qiu Ji Yang Benteng Ma Shuguang Lu Chuanhui Qin 2018Frontiers of Environmental Science & Engineering2018,12,6:2
8Synergistic regulation of dielectric-magnetic dual-loss and triple heterointerface polarization via magnetic MXene for high-performance electromagnetic wave absorption显示文摘The single dielectric/magnetic loss mechanism and invalid polarization loss are the crucial issues which limit the exploitation of multi-component electromagnetic wave(EMW)absorption materials,especially Ti_(3)C_(2)T_(x) MXene based absorption materials.In this work,a series of loosely packed accordion-like 3D NiCo/CeO_(2)/Ti_(3)C_(2)T_(x) with tunable and high-efficient EMW absorption were fabricated by introducing self-assembled NiCo alloys on the surface of Ti_(3)C_(2)T_(x) and subsequent anchoring of CeO_(2).On the one hand,the magnetic NiCo particles and highly conductive Ti_(3)C_(2)T_(x) achieved the dielectric-magnetic dual-loss.On the other hand,the triple interfacial polarization among NiCo/CeO_(2)/Ti_(3)C_(2)T_(x) further enhanced the relaxation loss.In addition,the effects of cerium ions on tuning the compositional structure,electromagnetic parameters and impedance behavior of the composites are explored.The NiCo/CeO_(2)/Ti_(3)C_(2)T_(x)-0.1 performed a wide absorption bandwidth of 6.32 GHz at 1.9 mm,as well as,the minimum reflection loss value of-42.48 dB at 2.0 mm.This work putted forward a new synergistic regulation strategy of dielectric-magnetic dual-loss and triple heterointerface polarization via magnetic MXene for high-performance EMW absorption,which may shed new light on the fabrication of multiple-component synergistic loss absorption materials.Chunhua Sun Zirui Jia Shuang Xu Dongqi Hu Chuanhui Zhang Guanglei Wu 2022Journal of Materials Science & Technology2022,,18:2
9Peroxidase-mimicking evodiamine/indocyanine green nanoliposomes for multimodal imaging-guided theranostics for oral squamous cell carcinoma显示文摘Here,evodiamine(EVO)and the photosensitizer indocyanine green(ICG)were integrated into a liposomal nanoplatform for noninvasive diagnostic imaging and combinatorial therapy against oral squamous cell carcinoma(OSCC).EVO,as an active component extracted from traditional Chinese medicine,not only functioned as an antitumor chemotherapeutic agent but was also capable of 68Ga-chelation,thus working as a contrast agent for positron emission tomography/computed tomography(PET/CT)imaging.Moreover,EVO could exhibit peroxidase-like catalytic activity,converting endogenous tumor H2O2 into cytotoxic reactive oxygen species(ROS),enabling Chemo catalytic therapy beyond the well-known chemotherapy effect of EVO.As proven by in vitro and in vivo experiments,guided by optical imaging and PET/CT imaging,we show that the theragnostic liposomes have a significant inhibiting effect on in situ tongue tumor through photodynamic therapy combined with chemodynamic chemotherapy.Zheng Wei Huihui Zou Gongyuan Liu Chuanhui Song Chuanchao Tang Sheng Chen Guorong Zhang Jianchuan Ran Yufeng Wang Xiteng Yin Yu Cai Wei Han 2021Bioactive Materials2021,6,7:2
10Sequential activation of uterine epithelial IGF1R by stromal IGF1 and embryonic IGF2 directs normal uterine preparation for embryo implantation显示文摘Embryo implantation in both humans and rodents is initiated by the attachment of a blastocyst to the uterine epithelium.For blastocyst attachment,the uterine epithelium needs to transform at both the structural and molecular levels first,and then initiate the interaction with trophectoderm.Any perturbation during this process will result in implantation failure or long-term adverse pregnancy outcomes.Endocrine steroid hormones,which function through nuclear receptors,combine with the local molecules produced by the uteri or embryo to facilitate implantation.The insulin-like growth factor(IGF)signaling has been reported to play a vital role during pregnancy.However,its physiological function during implantation remains elusive.This study revealed that mice with conditional deletion of Igflr gene in uteri suffered from subfertility,mainly due to the disturbed uterine receptivity and abnormal embryo implantation.Mechanistically,we uncovered that in response to the nidatory estrogen on D4 of pregnancy,the epithelial IGF1R,stimulated by the stromal cell-produced IGF1,facilitated epithelial STAT3 activation to modulate the epithelial depolarity.Furthermore,embryonic derived IGF2 could activate both the epithelial ERK1/2 and STAT3 signaling through IGF1R,which was critical for the transcription of Cox2 and normal attachment reaction.In brief,our data revealed that epithelial IGF1R was sequentially activated by the uterine stromal IGF1 and embryonic IGF2 to guarantee normal epithelium differentiation during the implantation process.Chan Zhou Meiying Lv Peike Wang Chuanhui Guo Zhangli Ni Haili Bao Yedong Tang Han Cai Jinhua Lu Wenbo Deng Xiaoyu Yang Guoliang Xia Haibin Wang Chao Wang Shuangbo Kong 2021Journal of Molecular Cell Biology2021,13,9:2
11Cephalopods-inspired Repairable MWCNTs/PDMS Conductive Elastomers for Sensitive Strain Sensor显示文摘Flexible electronic devices based on reversible bonds for self-curing capabilities arouses extensive interest.However,most of the composite conductive elastomers have the problems of poor mechanical properties and slow recovery of mechanical properties during multiple stretching,which hinder their stability in continuous operation.In this study,hyperbranched-MWCNTs/hyperbranched-PDMS self-healable conductive elastomers inspired by cephalopods were successfully developed.The prepared conductive elastomer exhibited good self-healing ability(91%)at room temperature excited by multiple reversible interactions.The prepared elastomer showed outstanding mechanical properties and anti-fatigue ability,so that it can cope with more arduous tasks.Moreover,the elastomer was sensitive to the change of stress states and can be used as a stable strain sensor.Therefore,the self-repairing conductive elastomer has potential practicability in the fields of human-computer interaction,motion monitoring,soft robot and so on.Kaiming Zhang Zhe Wang Yuetao Liu Haoyu Zhao Chuanhui Gao Yumin Wu 2022Chinese Journal of Polymer Science2022,40,4:2
